hello all,
I have requirement to identify similar records matching about 80% to 90%.I have to black list customers with multiple accounts.
The data is in the Oracle Database, but is there any way I can get the data into flat file and compare the strings and fetch similar matching records?
I have one table with
id
Name
middle_name
address
city
I need to pull out name and address fields similar. And spaces or slight difference can be ignored. I have tried within database methods which is very slow. And I have only basic knowledge of shell scripting need help for a way to get compared result faster. I have very large data to compare..more than 10 millions..
